-7

Explanation:

This is really a test of being very careful with your order of operations.

Will begin with what's inside the parenthesis:

-5color(red)(((-2)*(-8)-15))-2

Remove the parenthesis around -2 and -8

-5color(red)((-2*-8-15))-2

Following our order of operations we multiply first and then subtract. So...

-5color(red)((16-15))-2

-5(1)-2

Again, following our operations, we'll multiply -5 and -31 and then subtract 2:

-5-2

-7
